Planets do not emit any kind light on their own. How are they then detected from out of our solar system? Is it also not possible that we could have missed out some planet in our own solar system itself?

there are a few methods one can discover planets around a star.
1. it can be detected cause its mass is giving the star a specific movement, hence they both rotate around a shared center of gravity.
2. they may reflect light from the star and can be observed directly
3. they move in front of the star and darken its light, for a limited time

We see them by using the gentle from the solar that reflects off of them - a similar way we see all products that do not emit their very own gentle. for example this, go right into a gloomy room with a flashlight and a tennis ball. pretend the ball is a planet and the flashlight is the solar. Shine the gentle on the tennis ball - you will see it, even with the very undeniable truth that it would not emit any gentle. same with a planet, actually on a higher scale, and far farther away. we may be able to work out such issues as what chemical substances are in the ambience of planets, we may be able to work out at the same time as they get hit by using comets, we may be able to work out storms of their environment now and again, and so on - relies upon on how a ways away they are and how large the phenomenon being referred to is. best desires and God bless.

They do emit light.
Think of space as a dark room with dust flying around. If you turn on a flashlight you can see the dust reflecting the light. Out in space there are many flashlights such as stars that shine on an object such as a planet. Therefore we can see it. Just like if you go into space and look back at the earth it radiats light form the sun. The sun,therefore is the flashlight shining on the earth.
Hope this can help. HAVE A WONDERFUL DAY!!!

Planets in our own solar system reflect light from our sun and this is what astronomers look at to find them...
Planets around others stars have been found two ways that I know of…
1) By watching for the star to wobble from the gravitational pull of the planets orbiting it...
If you could view our sun from above or below the orbital plane of the planets from another star you would see it wobble as our planets orbit it…
2) By seeing the light of the star dim slightly as a planet passes between the star and us...

typically a planet is orbiting around a star which makes them reflect light. plus they have mass. yes we could have missed a planet in our solar system. probably because no one cares enough to look for it.

it does not emit light, but it reflects that's why we can see it. also some planets which cant b seen are discovered with the help of their mass and its effect on nearby heavenly bodies.

Its usually done by measuring a property know as gravitational wobble. The mass of the planet influences the star to change its orbit. these minor deflections are noted and the size and shape of the planet is computed...

They reflect light from the sun!
Any thing of any substantial size in the solar system would probably have been seen.

Well, the telescopes nowdays are really "smart". They detect unknown things. Another thing is the planets reflet the sun's light...Sometimes if something is affecting something orbit we find it out...(like neptune affected Uranus orbit)....good luck with this...

they emit light !! and it might be a possibility to find some new planets
